10. Every fight in the movie would be conducted entirely via Facebook or Twitter. And instead of breaking up physical fights in the hallway, Mrs. Norbury and Principal Duvall would have to learn The Youngs' Interwebs in order to discover the student body's fighting.

11. Aaron Samuels would have Snapchatted dick pics to Regina and probably Cady.

12. The Plastics would communicate mostly via text. Rather than three-way calls.

14. The video of the Plastics' "Jingle Bell Rock" talent show performance immediately would have gone viral. A boom box hitting a dude in the face? Hot high school girls in Santa hats? Please, it would be on Tosh.0 YESTERDAY.

15. Instead of comparing their flaws in a mirror, the Plastics would post selfies to Instagram. And make passive-aggressive comments on each others'.

16. Instead of tricking Regina into eating Kalteen bars, Cady would have swapped Regina's green juice for a protein shake. The kind gym rat dudes use to bulk up.

18. Instead of Abercrombie tanks and miniskirts, the Plastics would have worn skinny jeans and oversized sweaters. More Coachella, less Hello Kitty.

19. Karen would become a minor Internet celeb for her "weather ESP" breasts. And possibly end up vlogging wildly popular "haul" videos.

20. Instead of getting into sports, Regina George would grow up to be a contestant on The Bachelor. And very likely the bitchy blonde who starts drama among the other contestants. Competition is truly where she shines.
